RICHARD J. ROGERS, OF CHELSEA, MASSACHUSETTS, ASSIGNOR OF TVVO- THIRDSTO ALONZO B. ROGERS, OF SAME PLACE, AND JOHN M. BYRON,

OF BOSTON, MASSACHUSETTS.

OSCILLATING WATER-METER.

SPECIFICATION forming part of Letters Patent No. 373,608, dated November22, 1887.

(No model.)

.To all whom, it may concern.-

Be it known that I, RICHARD J. RoGERs, of Chelsea, in the county ofSuffolk and State of Massachusetts, have invented certain new and usefulImprovements in \Vater Meters, of which the following, taken inconnection with the accompanying drawings, is a specification.

My invention relates to meters for measuring fluids under pressure, andto that class of such meters as are usually termed piston meters; and itconsists in certain novel features of construction, arrangement, andcombination of parts, which will be readily understood by reference tothe description of the drawings and to the claims to be hereinaftergiven, and in which my improvements are particularly pointed out.

Figure l of the drawings is a vertical longitudinal section through theouter casing, and

showing the measuring-cylinder and other working parts in elevation.Fig. 2 isa longi tudinal section of the working-cylinder and a portionof the outer casing on line as a: on Fig.

1, and showing the remainder of the lower section of said casing inplan, the upper section or cover being removed. Fig. 3 is a transversesection on line y y on Figs. 1 and 2. Fig.

4 is a transverse section on line 2 2 on Figs. 1

and 2, and Fig. 5 is an end view of the bar or 0 yoke connecting thelocking-spindles.

In the drawings, A is the outer casing, made in two parts, each providedwith a horizontal flange, by which and suitable bolts said two parts arefirmly secured together, the line of division being above the center ofthe same, as

shown.

B is the measuringcylinder, provided with the trunnions a and b, thevalve-chambers c and d, the exhaust-passages e and 6, leading,

0 respectively, from the chambers cand d to the interior of the trunniona, and the portsf and f, leading, respectively, from the chambers c and(Z to the interior of the cylinder B at opposite ends thereof, as shownin Fig. 2.

C is the piston, fitted to reciprocate in said cylinder B and made ofgreater weight than the same bulk of water, for a purpose which willpresently appear. The cylinder B is mounted by its trunnions inhalf-boxes g g,

projecting inward from the vertical wall of the lower section of thecasing A, as shown in Figs. 2, 3, and 4.. The trunnion a has screwedinto it the discharge-pipe D, and the trunnion b has screwed into it thestem E, upon which may be mounted a lever (not shown) for op- 5 cratingthe register, (also not shown.)

The casing A is provided with the stuffingbox F, to pack thedischarge-pipe D, and the stuffing-box F, to pack the stem E and preventleakage around the same, and has cast upon its under side the feet A A,to support it in a horizontal position, and water is admitted theretothrough the pipe G. (Show'nin Figs. 3 and 4.)

The valve chambers c and d are each provided with two valve-seats, asshown at c and c in Fig. 3, with which the inlet-valve c and exhaust ordischarge valve 0 respectively engage alternately as the cylinder B isvibrated about its axis of oscillation, said valves being firmly securedupon the valve-stem h, which is fitted to a bearing, h, formed in theupper part of the chamber 0 or d, while the pistonlike valve 0 is guidedin a bearing in the lower end of said chamber a or d, the ends of saidvalve stem h abutting against the lugs or shoulders and 2" formed,respectively, in the upper and lower portions of the casing A, all asshown in Fig. 3.

In the center of each of the heads B of the cylinder B is mounted so asto be movable endwise therein a pin, j, which has formed upon its outerend a head, j, in which are formed the two grooves j to receive theforked ends of the bar-or yoke H, the end portions 85 of which are bentat right angles to the main body and forked, as shown in Fig. 5, the barH being fitted to bearings it on the cylinder B, all so constructed andarranged that when the piston O is moved in the direction indio cated bythe arrow on'Fig. 2 "and approaches the end of its movement in thatdirectionit will strike the pinj in the right-hand head of the cylinderB and move it outward until said piston strikes the hub on theinner-sideof said 5 head, and at the same time,through the medium of the bar H,will move the pinj in the head at the left-hand end of said cylinderinward an equal distance and disengage it from the locking-lever J andcause the leather packingring l on said pin to pack the joint aroundsaid pin and prevent leakage around the same.

I I are two stands secured to the lower section of the case A, one ateach end, to the upper end of each of which is pivoted the pendentlocking-latch J, the shoulder m of which engages with the upper surfaceof the head j of the pin j, as shown at the left of Fig. 1, to lock thecylinder in the position with its left-hand end depressed, as shown inFig. 1.-

Ihe operation ofmyinvention is as follows: The parts being inthepositions shown in the drawings and the casing being filled with waterunder pressure, if the faucet be opened to draw water therefrom, waterwill enter the valvechamber at beneath the inlet-valve a at the left ofFig. 1, and, flowing through the portf into the cylinder B, will movethe piston Otoward the righthand end of the cylinder B un til saidpiston comes in contact with the hub of the right-hand head B, having inso doing moved the pinsjj and bar H in the same direction, and therebywithdrawn the head j of the pin j at the left of Fig. 1 from beneath thelocking-lever J, when the excess of weight in the right-hand end of thecylinder will cause that end thereof to be depressed until thelocking-lever J at the right of Fig. 1 engages with the head j of thepinj and locks'said cylinder in that position. At the commencement ofthe operation the inlet-valve c at the left and the exhaust-valve 0 atthe right of Fig. 1 were open and the other two valves were closed; butthe depressing of the right-hand end of the cylinder causes the closingof the left-hand inlet and the righthand exhaust or discharge valves andthe opening of the right-hand inlet and the left-hand exhaust ordischarge valves, when the water will enter the right-hand end of thecylinder through the valvechamber c and the passage f to move the piston0 toward the left again, the water in said cylinder at the left of thepiston passing through thepart f into the chamber (1, thence between theseat 0 and the valve 0 at the right of Fig. 1 to the lower part of saidchamber d, thence along the passage e to the interior of the trunnion a,and thence through pipe D to the faucet. These operations will berepeated as long as the faucet remains open.

What I claim as new, and desire to secure said cylinder and thedischarge-valve being opened and the inlet-valve closed at the other endof the cylinder by the same movement of the cylinder.

2. In a water meter, the combination of a fixed water chamber orreservoir provided with a water-supply pipe, an oscillating cylindermounted in said reservoir and provided with independent valve-chambersfor each end thereof, a piston of greater specific gravity than water,arranged to move endwise in said cylinder, and an inlet and dischargevalve in each of said valve-chambers, both mounted in fixed positions ona valve-stem, all arranged and adapted to operate substantially as andfor the purposes described.

In testimony whereof I havesigned my name to this specification, in thepresence of two subscribing witnesses, on this 2d day of August, A. D.1887.

RICHARD J. ROGERS.
